One of the HostGator former admins actually doxxed one of my old accounts on reddit by typing my full name in response to some random comment. When I asked him how he knew it, it's because my reddit username was the same as my domain name at the time, and he remembered looking through my server. Whenever the admins would get bored, they'd just dig through peoples' servers and see what they had. He remembered mine because I had a lot of sheet music on it.
They get people like this because they put their admins through the puppy mill process. Basically hire anyone not braindead, train them to do basic shit, and then pay them peanuts. The company men eventually get a high position in the hierarchy for a negligible pay bump and then help keep the new ones in line.
Such a shitty company, but I don't host anything sensitive there and it's been reliable for the last 10 years so I haven't migrated anything yet.
